LUCY (NASA SPACECRAFT)

Trojans are a large group of asteroids that share Jupiter's orbit around the Sun. These Trojans orbit in two loose groups one group is always ahead of Jupiter and the other always behind. They hold clues to the history of solar system including the fossils of planet formation and perhaps even the origins of life. So in order to study these Trojan asteroids NASA has planned their Lucy mission. Lucy will be launched in year 2021. It will travel all the way to these Trojans and spend 12-years studying 7 different Trojans and asteroids from asteroid belt. This Experiment Went for 91 Years!

Launching in late 2021, Lucy will be the first space mission to explore the Trojan asteroids. These are a population of small bodies that are left over from the formation of the solar system. They lead or follow Jupiter in their orbit around the Sun, and may tell us about the origins of organic materials on Earth. Lucy will fly by and carry out remote sensing on six different Trojan asteroids and will study surface geology, surface color and composition, asteroid interiors/bulk properties, and will look at the satellites and rings of the Trojans.

This visualization includes multiple views of the entire Lucy mission in a Jupiter-rotating reference frame. The visualization includes top-down, side, and oblique views of the solar system. Jupiter's swarms of Trojan asteroids may be remnants of the primordial material that formed the outer planets, and serve as time capsules from the birth of our Solar System more than 4 billion years ago. The Trojans orbit in two loose groups that orbit the Sun, with one group always ahead of Jupiter in its path, the other always behind. At these two Lagrange points the bodies are stabilized by the Sun and Jupiter in a gravitational balancing act. These primitive bodies hold vital clues to deciphering the history of the solar system, and perhaps even the origins of life and organic material on Earth. Lucy will be the first space mission to study the Trojans. The mission takes its name from the fossilized human ancestor (called “Lucy” by her discoverers) whose skeleton provided unique insight into humanity's evolution. Likewise, the Lucy mission will revolutionize our knowledge of planetary origins and the formation of the solar system. Lucy will launch in October 2021 and, with boosts from Earth's gravity, will complete a 12-year journey to seven different asteroids — a Main Belt asteroid and six Trojans, the last two members of a “two-for-the-price-of-one” binary system. Lucy’s complex path will take it to both clusters of Trojans and give us our first close-up view of all three major types of bodies in the swarms (so-called C-, P- and D-types).

Scientists have had the opportunity to examine several asteroids in the Solar System now, and what they’ve learned is how much variety is out there, depending on the mass, distance from the Sun and composition. Astronomers currently know of 829,400 asteroids across the Solar System, and they’d love to visit as many of them as possible to learn more about them. Considering the price of a single spacecraft, that’s going to get expensive. Fortunately, there are places in the Solar System that have trapped a large number of asteroids in a way that a single spacecraft can visit several of them as part of a mission. They’re at Jupiter’s L4 and L5 Lagrange points, and this week NASA approved a new mission that’ll explore 7 different asteroids over a 12-year journey. It’s called Lucy.

Beyond the asteroid belt are "fossils of planet formation" known as the Trojan asteroids. These primitive bodies share Jupiter's orbit in two vast swarms, and may hold clues to the formation and evolution of our solar system. Now, NASA is preparing to explore the Trojan asteroids for the first time. A mission called Lucy will launch in 2021 and visit seven asteroids over the course of twelve years - one in the main belt and six in Jupiter's Trojan swarms. Lucy is named for the famous hominid fossil that shed light on our early human ancestors; by making the first exploration of the Trojan asteroids, the Lucy mission will improve our understanding of the early solar system, and be the first to uncover these fossils of planet formation.

Dr. Hal Levison joined the NASA Night Sky Network on July 25, 2019 to share with us the plans for the Lucy mission to study the Trojan asteroids.

With two new missions set by NASA, we hope to learn so much more of the asteroids surrounding Jupiter's orbit and the origin of our moon!
